For reliable performance and consistent results, choose HP original ink cartridges. Designed with the new JetIntelligence technology, these innovative cartridges utilise smaller, more robust components, as well as ColorSphere 3 toner, to improve performance and increase page yield by up to 33%. ColorSphere toner has a softer core for faster melting and smoother flow onto the page, but its harder shell reduces toner wear for longer life. Compatible with HP Color LaserJet M552 and M553, this magenta toner has a page yield of up to 6000 pages.
